The Colt 1877 also known as the Lightning and the Thunderer was Colt's first attempt at a double action revolver produced from January 1877 to 1909. Colt introduced the 1877 to compete with their British rival Webley and their Bulldog revolver. Today the double action Colt 1877 is not produced by any gun company, but single action versions almost identical to the 1877 are produced by Cimarron. The ammuniton for the revolver are still being produced.
